Overview
Description
Figure 1 View of devices
SITOP PSU400M is a power supply for DC link voltages of drive systems. If the power fails,
the energy of the flywheel mass and in the DC link capacitors is used to maintain the 24 V
supply for the electronics. As a consequence, axes can be stopped or retracted in a
controlled fashion. This can prevent expensive workpieces from being destroyed.
The key benefits of the product include:
● Rated input voltage 600 V DC
● Operating voltage range 200 (300) - 900 V DC
● High degree of efficiency up to 95 %
● Output voltage can be adjusted in the range 24 - 28.8 V
● Ambient temperature -25 ... 70 °C (derating from 60 °C)
● Brief overload capability of 150% for 5 s/min (extra power)
● No lateral mounting clearances are required
● Selectable short-circuit behavior
● Soft characteristic for parallel switching can be selected
● integrated signaling contact for "24 V O.K."

WARNING
Correct handling of the devices
When operating electrical devices, it is inevitable that certain components will carry
dangerous voltages.
Therefore, failure to handle the units properly can result in death or serious physical injury
as well as extensive property damage.
Only appropriately qualified personnel may work on or in the vicinity of this equipment.
Perfect, safe, and reliable operation of this equipment is dependent on proper
transportation, storage, installation and mounting.
Before installation or maintenance work can begin, the system's main switch must be
switched off and measures taken to prevent it being switched on again.
If this instruction is not observed, touching live parts can result in death or serious injury.

SITOP PSU400M is a primary-clocked power supply for connection to DC supply voltages
(e.g. to the DC link voltage of drive systems). An electronically regulated DC voltage that can
be set via a potentiometer is available at the output of the device. The output of the device is
isolated, no-load proof and short-circuit proof. The LED display indicates the operating
status. The operating state of the device can be processed via the signaling contact.

2.1 Device description
The 6EP1566-3AA00 voltage rise limiter is used as ballast for the PSU400M 24 V/20 A
power supply.
A filter is integrated in the ballast to improve the EMC of power supply PSU400M (only
applicable for product version 1).
It is not permissible that a 6EP1566-3AA00 ballast device is connected in parallel or in series
with a second ballast device.

The potentiometer ④ on the front of the device is used to adjust the output voltage. The
output voltage is set to 24 V in the factory, and can be adjusted in the range 24 - 28.8 V; for
example, to compensate voltage drops across long supply lines to the connected load.

When adjusting the output voltage to > 24 V, the output current must be derated by 4 %/V,
or the permissible ambient temperature must be taken into account with 3 °C/V.

capacitances in this operating mode at the
